The mandibles, like the antennae, have, in the nauplius, the form of biramous swimming limbs, with a masticatoryprocess originating from the proximal part of the protopodite.
In the nauplius larva they lie rather at the sides than in front of the mouth, and their basal portion carries a hook-like masticatory process which assists the similar processes of the mandibles in seizing food.
